Right to die campaigner Paul Lamb says he does not understand why Supreme Court judges have decided against him.
Both he, and the family of the late Tony Nicklinson wanted the law changed to allow doctors to assist patients to die.
A third man, Martin, wanted the current prosecution guidance on assisted suicide clarified.
However, the UK Supreme Court has ruled that the current law breaches the right to a private life.
Paul Lamb spoke to reporters outside court.
